Terminal, wireless communication method, base station, and system

Abstract

A terminal according to one aspect of the present disclosure comprises: a reception unit which receives first downlink control information (DCI) that schedules a physical downlink shared channel (PDSCH), or second DCI that schedules an aperiodic channel state information reference signal (A-CSI-RS); and a control unit which, in the case where the value of the period from the reception of the first DCI to the reception of the PDSCH is smaller than a first threshold when an upper layer parameter which validates two states of default transmission configuration instruction (TCI) is not configured, determines a default TCI state to be applied to the PDSCH, and in the case where the value of the period from the reception of the second DCI to the A-CSI-RS reception is smaller than a second threshold when the upper layer parameter is configured, determines a default TCI state to be applied to the A-CSI-RS. According to the one aspect of the present disclosure, an operation pertaining to the default TCI state / a spatial relationship / a pathloss reference signal can be suitably controlled.
